AUXILIARY CARB'URETEB.

Application filed February 25, 1919.

' To all whom it may concern:

Be it known that I, PETER J. LYNoH, citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, hav invented certain new and useful Improvements in Auxiliary Carbureters, of which the following is a specification.

This invention relates to an improved auX- iliary carbureter for internal combustion engines which will be of simple construction, which may be readily replenished, and which will operate with entire efficiency.

Other and incidental objects will appear hereinafter. In the drawings:

Figure l is a fragmentary side elevation showing my improved device in connection with a conventional type of internal combustion engine, and

Fig. 2 is a vertical sectional view on a slightly enlarged scale, this view more particularly showing the details of construe-- tion of the device.

In carrying the invention into effect, I employ a container 10. This container may be constructed of any approved material but is preferably in the nature of a glass jar so that the level of the contents of the container may be at all times easily observed. Removably threaded upon the upper end of the container is a closure cap 11, a sealing gasket being preferably employed between the flange of the cap and the container. The cap 11 is formed with a top wall 12 provided with a central depressed portion 13 defining chamber 14: upon the cap and providing an annular shoulder 15 at the periphery of this chamber. Seating against said shoulder is a plate or disk 16. This plate closes the chamber at its upper side and is soldered or otherwise secured-to the shoulder. Formed through the bottom wall of said chamber is an annular series of spaced openings 17 which serve to break up the large globules of kerosene suspended in the air and thus homogenize the mixture. A marked uniformity in the mixture delivered by the device is thus obtained. Leading from the upper portion of the chamber is a suction pipe 18 suitably secured at its inner end to the disk 16. Leading through the top and bottom walls of the chamber 14: and fixed upon the cap is an inlet pipe 19 provided at its upper end with a filler cup 20 and terminating at its lower end in a coil 21 lying close to the bottom wall of the container parallel thereto. The coil is,

fold 241 to the lower end of which is con nected a carbureter as conventionally illustrated at 25. The device may be arranged at any suitable point adjacent to the engine and, as clearly shown in Fig. 1, the suction pipe 18 is led from the device and suitably connected with the manifold trunk or other approved portion of the manifold between the engine carburetor and the engine, a coupling being interposed in the length of the pipe so that, when desired, the container may be readily detached from the manifold. With the device thus connected with the engine, a quantity of kerosene is poured into the filler cup 20 and thus introduced into the container, care being taken that the coil 21 is at all times submerged. Consequently, when the engine is started, the engine suction will be communicated through the pipe 18 to the container so that air will be drawn in through the inlet pipe 19 displacing the liquid therein so that the air can escape through the openings 22 of the coil 21 at the bottom of the container. The air so drawn in through the inlet pipe will then, of course, rise upwardly through the body of kerosene in the container, thus carbureting the air. This carbureted air will be drawn through the opening 17 and thence carried off through the pipe 18 to be introduced into the manifold 24 of the engine. Thus, while the engine is running, a mixture of kerosene and air will be constantly introduced into the manifold to be mingled with the fuel mixture from the carburetor 25 and delivered to the engine cylinders.

The device is of exceedingly simple construction and may, with slight difficulty, be readily connected to substantially any conventional type of internal combustion engine. In this connection it is to be observed that when the device is once installed it will be unnecessary to detach the device in order to accomplish the filling thereof, owing to the provision of the filler cup 20 upon the inlet pipe 19. However, should any trouble develop in connection with the device, the

upon the dis coupling in the suction pipe 18 may be released when the container may be removed, the cap detached and the filler pipe and coil 21 displaced from the container. The coil may consequently, when found necessary, be easily flushed for removing any stoppage therein so that the device may, at

all times, be maintained to operate with en tire efliciency.

As will be noted, the disk 16 will reinforce the top wall of the cap 11 while the pipe 19, which extends through said disk and through the top wall of the cap, will, in being fixed to the top wall, serve to brace the disk and hold said disk against possible dislocation, the cap being provided, as shown in Fig. 2, with a shoulder overhang ing the disk fOr resisting upward strain upon the disk such as might be brought about through the presence of the pipe 18 Having thus described the invention, what is claimed as new is:

an auxiliary carbureter including a container, a cap closing the container having a top wall, the top wall of the cap being depressed to provide a central recess, a plate overlying the depressed portion of the wall and secured thereto closing said recess to define a chamber, the depressed portion of the wall being provided with a plurality of small openings therethrough leading from the container into the chamber, an air inlet pipe extending through the plate and said wall into the container, the pipe coacting with the plate and being secured to the wall for bracingand retaining said plate, and an outlet pipe connected to the plate leading frorn'the chamber.

In testimony whereof I aiiix my signature. 40
